Abstract
The utility model relates to the technical field of gate valve, in particular to a gate valve provided with a pneumatic valve rod, which includes a flashboard, a valve body, a valve rod, a handwheel, flow channels and a valve chamber. The gate valve is characterized in that the inside of the valve rod is provided with a pneumatic hydraulic part; the inlet of the valve chamber of the flow channel is provided with a spacing ring; and the flow channels ahead and behind the flashboard are respectively provided with a filter screen. Compared with the prior art, the gate valve uses a pneumatic hydraulic power assisting device which has the advantages of simple and convenient structure, simple installation and maintenance, low pressure grade, safe use, etc, and the gate valve with the pnumatic valve rod can be assembled with the valve rod to realize that the starting and closing time of the gate valve is reduced, and the stroke can be operated and controlled easily, thereby improving the work efficiency.
Description
[technical field]
The utility model relates to the gate valve technical field, specifically a kind of gate valve that is provided with pneumatic valve rod.
[background technique]
Gate valve is a kind of common valve, plays a part to cut off the pipeline medium, is widely used in the industries such as oil, chemical industry, metallurgy, mine, thermoelectricity plant, and gate valve mainly is made up of parts such as valve body, valve gap, valve rod, flashboard and handwheels.According to the structural type of flashboard, flashboard can be divided into wedge-type and parallel type two big classes, and in the gate valve of ordinary construction, valve rod is connected with the valve gap place by screw thread.All there is following shortcoming in existing dissimilar gate valve: opening and closing time is long, and is highly big, because gate valve must standard-sized sheet or complete shut-down when opening and closing, gate travel is big, open with will certain space, and the boundary dimension height, installation footprint is bigger.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, sets up Pneumatic actuator in valve rod inside, operates automatically.
In order to achieve the above object, the utility model proposes a kind of gate valve that is provided with pneumatic valve rod, comprise flashboard, valve body, valve rod, handwheel, runner, valve chamber, it is characterized in that: valve rod inside is provided with the Pneumatic Liquid casting die, is provided with limited ring at the valve inlet chamber place of runner; Be respectively equipped with filter screen in the runner before and after the described flashboard.
The utility model is compared with prior art, utilizes advantages such as the pneumatic hydraulic power assisting device is simple in structure, light, installation and maintenance are simple, and pressure rating is low, event is safe in utilization.This device is assemblied in the valve rod, and it is short to have reached the gate valve opening and closing time, and stroke is controlled simple and easy, thereby has improved working efficiency.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is flashboard, and 2 is limited ring, and 3 is valve chamber, and 4 is valve rod, and 5 is the pneumatic hydraulic power assisting device, and 6 is filter screen.
[embodiment]
Now in conjunction with the accompanying drawings the utility model is described further.
Referring to Fig. 1, valve rod 4 inside are provided with pneumatic hydraulic power assisting device 5, utilize the compressibility of air, but storing energy released energy in the short time, to obtain valve rod ground high-speed response, simultaneously can make Pneumatic actuator that the self-sustaining ability is arranged, keep the uphill process of valve rod slowly steady.Valve chamber 3 ingress at runner are provided with limited ring 2, and limited ring 2 can make valve rod 4 control bit that seizes up after opening fully, MEDIA FLOW through the time, under the ambient conditions complicated situations such as pressure, keep size.Be respectively equipped with filter screen 6 in the runner of flashboard 1 front and back, just be applied to keep in the different operating environment runner monotony at every turn.
Claims (2)
1. a gate valve that is provided with pneumatic valve rod comprises flashboard, valve body, valve rod, handwheel, runner, valve chamber, it is characterized in that: described valve rod (4) inside is provided with pneumatic hydraulic power assisting device (5), is provided with limited ring (2) in valve chamber (3) ingress of runner.
2. a kind of gate valve that is provided with pneumatic valve rod according to claim 1 is characterized in that: be respectively equipped with filter screen (6) in the runner before and after the flashboard (1).
